Engine Performance problem
1996 Chevy Astro 6 cyl Two Wheel Drive Automatic 132000 miles
Engine runs rough when it is humid or raining outside. Replaced Cap, Rotor, plugs, wires. Still misfires, runs rough. Looked under the hood when it was wet outside but couldn't see anything wet under there. Otherwise engine runs perfect, starts right away, idles great. Misfires soon as step on gas pedal.
Tired of paying for diagnostic test!
have the same problem?
